Your Bernoulli idea may have some merit.

As for precession, you are missing the point. What you are implying is that precession can happen without a displacement. If you study precession with an open mind, maybe do an experiment, you will come to a better understanding of it.

I'm not sure I understand what you keep saying about motion causing a force. You seem to be implying that that is what I'm saying. It is not. Precession is a reaction to displacement, which is caused by a force. If you don't see by the FAA's explanation that the propeller's plane of rotation has to rotate, you have much of the right idea, again, you are just missing the point.

Don't be stubborn. Study it carefully and you will be rewarded.

The fact that a propeller is moving air does not affect its gyroscopic properties. Toy gyros have an effect on air as well.

The universe stuff was a joke.

If you are suggesting that I am one of those people who has a lot of theoretical knowledge yet doesn't "get it", think again. I do have some theoretical knowledge, but I can more than back it up with 27 years of modeling experiece, full-scale aerobatic competition and 4600 hours full-scale flight time, most of it professional, and an Airline Transport Pilot Certificate. Also, four years professional UAV R&D and revenue flight experience.
